ABSTRACT:
A glassware forming machine including means for distributing gobs of molten glass to individual sections of the machine at a predetermined rate, drive means responsive to electrical power of a selected frequency generated by a power source for driving the gob distributing means at the predetermined rate and an automatic control means responsive to timing signals for controlling each of the individual sections in a predetermined timed sequence of steps for forming the glassware wherein the power source generates the timing signals at a frequency proportional to the selected frequency of the power source. Each piece of glassware is formed during a machine cycle which is related in duration of the gob distribution rate and typically is defined in terms of 360.degree.. The power source includes means for generating a reference signal at a frequency which determines the selected frequency of the electric power and means responsive to the reference signal for generating the timing signals at the frequency required for defining 360.degree. per machine cycle.
